'-------------------------------------------------
福建 厦门 思明 黄厝 曾厝桉村
福建 泉州 丰泽 西湖 水头村
如上面的五级转成数据库为:
'-------------------------------
id filed1 filed2 filed3
1 0 0 福建
2 1 1 厦门
3 1 1 泉州
4 2 2 思明
5 3 4 黄厝
6 4 5 曾厝桉村
7 2 3 丰泽
8 3 7 西湖
9 4 8 水头村
'-------------------------------------------------
数据库说明:
id 自动编号
filed1 下拉菜单列表的等级(看级数。可以设置它的菜源码源码空间delphi精度。是菜源码数字类型)
filed2 上一级的id号(用长整型吧)
filed3 这个就不用说了吧(文件。长度自己看情况)
本程序在IIS4+WINP+ACCESS下通过。菜源码
